Rubber composition for adhering to steel cords |
(57) The invention aims at providing a rubber composition for adhering to steel cords
which is excellent in heat-resistant adhesion and moist heat-resistant adhesion as
well as initial adhesion and has performance of a level similar to or higher than
that of the related art in resistance to rubber fracture, wherein the following components
(A) and (B) are blended to 100 weight parts of rubber components containing natural
rubber and/or diene synthetic rubber:
- Component (A) : a mixture of a compound containing nickel and a compound containing
molybdenum; or a compound containing nickel and molybdenum simultaneously in a metal-converted
amount of 0.01 to 10 weight parts.
- Component (B):(b1) 0.2 to 20 weight parts of hexamethylenetetramine or a melamine
derivative, and(b2) 0.1 to 10 weight parts of at least one selected from the group
consisting of phenol resins, resorcin, resorcin derivatives, and cresol resins.
